Answer:
The answers for your question is 0.17
The formula of interest is
A = (1/2)r²·θ
You have r = 9 m, θ = 3π/5. Then the area is
A = (1/2)(9 m)²(3π/5) = 24.3π m²
The sector area is ...
A ≈ 76.3 m²
Answer:
y = (1/3)x +5/3
Step-by-step explanation:
The general equation of a line is
y = mx+b
where m is the slope and b the y-intercept
Since the slope is 1/3 we have
y = (1/3)x +b
since the line passes through (x,y) = (-2,1) this point satisfies the equation
1 = (1/3)(-2) + b ===> b = 1+2/3 ===> b = 5/3
and the equation of the line is
y = (1/3)x +5/3
His answer is correct because if you have the pie chart, it shows the percentage. <span>he did 45 times 3 to get the 135 because he though since 10% is 45 people he could multiply by 3 & get his answer.
Hope this helped.</span>
